This invention relates to bumpers. It is the object of this invention to provide a bumper in which the parts are securely attached together. It is also an object of this invention to provide a bumper in which the parts are reduced to a minimum and are so constructed, with relation to each other, as to be secure, iirm and effective for the purpose for which they are intended.

It is the purpose of this invention also to provide a bumper in which each of the parts is vwelded to another part to form a bumper in which the structure is essentially, when completed, composed of one piece of metal.

It is an object of this invention to provide a bumper of this type in which the parts are so constructed and related to each other that they are firmly welded to form a bumper sub stantially of one continuous piece ot' metal.

For the purpose of illustration the accompanying drawings present a preferred embodiment.

In the drawings:

Figure l shows a face view of the bumper bars detached from the other parts.

Figure 2 is a plan view oit the completed bar.

Figure 3 is a face view of the bumpers in their completed condition, showing the clamp 3o members associated therewith.

Figure 4 is an enlarged view showing the rear of the clamp bar attached to the bumper bars.

Figure 5 is a cross section on the line 5-5 of Figure Ll.

Figure 6 is a back View of one end ot the bumper bars, showing the end plate and its manner of attachment to the bars.

Figure 7 is a cross section on the line 7-7 of Figure 6.

This device is composed essentially of three bars, two of which are bumper bars and the other of which is a back bar. The bumper bars, indicated by the numeral l, are arranged parallel with each other and slightly apart. In each of these bars, near the ends thereof, are holes 2. These holes are adaptedv to receive a stud, later on described.

Conveniently attached to the bun-iper bars,

5 and for the purpose of holdilfigl the bars in 1928. Serial No. 295,416.

their proper spaced relation to each other and for the purpose of providing u support therefor, there is a back bar 3. This back bar is bent at each end-in the form of a loop, the free ends of which are attached to the bumper bars, as indicated by the numeral Ll.

For the purpose oi' attaching the two bumper bars together, in connection with the holes 2, there is a clamp plate 5. This clamp plate has an intermediate stud 6, which lits between the .two parallel bumper bars and holds them in spaced relation. Near the end of the clamp member 5 there are two stud members 7, which project through the holes 2. The stud 6 is just long enough to reach through the space between the bumper bars and be flush with the back surface thereof, while the studs 7 extend beyond the back limits of the holes 2.

The looped ends ot the back bar 3 are adapted to fit over the space between the bumper bars at the point where the stud 6en gages the two bars. The inner faces of the outer ends of the studs 7 are beveled, and between these two faces the looped ends ot' the back bar 3 fit.

vWhen the back bar is placed in position with its looped ends engaging the bumpers at the point where the clamps 5 are in engagement with the bars, the studs 7 project along the sides of the back bar and extend to a line Hush with the bac r side of the Vback bar. When the back bar is in the position here described there is a wedge shaped opening be tweenvthe studs 7 and the back bar. For the purpose of attachingthe parts securely together the studs 7, the back bar 3 and the bumper bars 1 are welded together at the point 8, which also indicates the beveled surface on the studs 7.

The shape of this surface, which might be called a weld cup, is better shown and ilf lustrated in Figure 4. The cup part does not extend entirely across the lugs 7, but is scooped out to iiorm a kind of a trough with the ends closed.

For the purpose of securely fastening the parts together they are welded by means of some suitable welding method or process, by which the cavity formed by the weld cup is entirely Closed up in the process of Welding.

'in bumper bars.

In Welding the parts, as here shown, a piece of filling material is used as one of the electrodes and melts directly into place in the cups to be filled. By this process of Welding the front parts of the bumper, which may be in its linished polished state, are not marred or affected by the process of Welding.

The same method of Welding is used in connection with the plate clamps at the ends of the bars. These clamps arevindicated by the numeral 9, and have extendingr therefrom a stud l0, which has in each face thereof a Weld cup l1. The stud l() lits in between the bumper bars near the ends thereof, and is adapted to hold the bars in spaced relation to each other. This stud l() may be longer than'the plate clamp, but is not intended to extend beyond the ends of the bars.

For the purpose of securely fastening the bars together with the plate clamps secure; thereto. the parts are Welded in a manner similar to that described in connection with what might be called lthe bar clamps. Suitable welding material is applied to the space formed by the weld cup in connection with the edge of the bumper bars. 'I his welding material heated in connection with the adjoining surface of the bumper bars and the stud 10 so that a secure and permanent Veld is effected.

The ends of the bars are curved, as indicated in Figure as is usually the custom The plates may be of any ornamental design and are primarily used for the purpose of clamping the parts in firm and secure relation to each other.

By this process and method applicant has formed a bumper in which the parts are securely attached together, and one that is capable of bearing` a `good deal of heavy strain.

I desire to comprehend Within my invention such modifications as may be clearly embraced within my claims and the scope of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

l, In a bumper, a pair of bumper bars, each bar having` a series of holes arranged therein in the same relative position to each other,

clamp means having studs thereon and projecting through the holes in the bars and a d apted to hold the bars in fixed spaced relation to each other, the bars and the clamp' means being permanently united to form a rigid bumper.

Q. In a bumper, a pair of bars held in spaced' rela-tion to each other and having a series of holes in each bar,.a backbar, means engaging the bumper bars and extending through' the holestherein and also engaging the back bar, and integrally attached to the bumperv 'bars and the back harto hold them inrig-id fixed relation' to each other.

3, Inafbumper, ap air! ofbumperharsh-eid;

in spaced relation With each other, each bar having a series of holes arranged therein, the holes of one bar being adjacent the holes in the other, a clamp plate having a stud near the center thereof adapted to extend through the space between the bars, and a stud adjacent each end adapted to extend through the holes in the bumper bars and means for uniting the plate and the bumper bars at the point Where the studs pass through said holes.

e'. In a bumper, a pair of bumper bars held in spaced relation to each other having a series of adjacently arranged holes therein, a back bar attached to said bumper bars across the space therebetween and means extending through the holes in the bumper bars and contacting the back ba-r to hold the bumper bars and the back bar in rigid integral relation to each other.

5. In a bumper, a pair of bumper bars, each bar having a series of holes arranged therein in the same relative positions to each other, and a clamp means having studs thereon projecting through the holes in the bars to hold the bars in fixed spaced relation to each other, the bars and the clamp means being Welded together to form a rigid bumper.

6. In a bumper, a pair of spaced bumper bars, and a lock bar engaging one side of said bumper bars and havingmeans integral with the back bar to engage the other side of said bumper bars to hold said bumper bars to the lock bar and in spaced relation to each other.

In testimony whereof, I affix my signature.
